Describe your issue

Accessing an itemstack's components through itemstack.components.get() or itemstack.get() returns an object with no properties or methods to access the component data, making them unusable to my knowledge.

The below, when placed in server_scripts will net us an object named BundleContents[2 minecraft:dirt] for a player whose first slot contains a bundle with 2 dirt blocks inside.

PlayerEvents.chat(event => {
  console.log(event.player.inventory.getStackInSlot(0).get('minecraft:bundle_contents'))
})

As the only other way to get component data is through itemstack.componentString, we have to mutate a string into an array, then manipulate its values before replacing the bundle data with itemstack.setBundleContents()
